and a darker and broader one on each side, appearing at times in hordes 

 of countless thousands, devouring vegetation of various kinds, but espe- 

 cially grains and grasses. The adult moths spread about IV2 inches 

 from tip to tip of the wings and are brownish-yellow in color. 



Injury in North Carolina. — Very few outbreaks of this 

 insect have been reported to us, although it is certainly 

 present in at least limited numbers every year. Adult 

 moths are often found at Kaleigh from May to JSTovem- 

 ber. We have one adult moth captured by the writer at 

 Hendersonville in June, 1907. The indications are that 

 it occurs throughout the State, but that its area of de- 

 structiveness is chiefly in the western half. 



In 1907, three complaints of damage by it were received 

 from the mountains, but in no case was the outbreak re- 

 ported as widespread. The complaints were all in May. 



In August, 1908, while the writer was in the western 

 part of the State on Institute work, news of an "Army- 

 worm" outbreak came from Durham, IST. C, and this was 

 looked into by Assistant Z. P. Metcalf, some of whose 

 observations will be presented later in this account. 



Life-history, Habits, etc. — There are undoubtedly sev- 

 eral broods of this insect each year, for at Raleigh the 

 moths have been collected from May to November by Mr.

C. S. Brimley. Dr. Forbes^ states that only one brood is apt to be de- 

 structive in any one locality in any one year. This agrees with the 

 reports which have come to us; and observations in 1908 indicate that 

 there is a good reason. It is believed that the winter is spent in the
